原生php生成在线数据库字典,采用mysqli扩展链接，支持php7
在项目根目录新建show_table.php
修改几个define常量参数访问show_table.php即可

<?php


header('content-type:text/html;charset=utf-8');
define('DB_HOST','地址');
define('DB_USER','账号');
define('DB_PASS','密码');
define('DB_NAME','数据库');
define('DB_PORT','端口号');
define('DB_CHAR','utf8');
define('APPNAME','XX项目');
@$conn=mysqli_connect(DB_HOST.':'.DB_PORT,DB_USER,DB_PASS);
mysqli_select_db($conn,DB_NAME);
mysqli_query($conn,'set names ' . DB_CHAR);
//$sql="SHOW TABLE STATUS FROM " . DB_NAME . ' where Name like "jm_crm_%"';
$sql="SHOW TABLE STATUS FROM " . DB_NAME;
$result=mysqli_query($conn,$sql);
$array=array();
while($rows=mysqli_fetch_assoc($result)){
    $array[]=$rows;
}
// table count
$tab_count = count($array);
